ESCUTCHEON-PLATE.

SPECIFICATION forming part of Letters Patent No. 695,472, dated March18, 1902. Application filed July 22, 1901. Serial No. 69,276. (Nomodel.)

To ctZZ whom, it may concern:

Belt known that I, J AMES B. MILLER, a citizen of the United States,residing at Kent, in the county of Portage and State of Ohio, haveinvented a new and useful Improvement in Escutcheon-Plates, of which thefollowing is specification.

My invention relates'to an improvement in escutcheon-plates for door anddrawer locks; and the object of my invention is .to provide anescutcheon-plate that adds to the security of the lock with which it isused. I attain this object by the form and construction illustrated inthe accompanying drawings, in which- F'gure 1 is a frontelevation of myimproved escutcheon-plate, a portion of a door, and a portion of aface-casing of the doorframe; Fig. 2, a partial sectional plan on thebroken line a w of Fig. 1, and Fig. 3 an edgewise elevation, of myimproved escutcheon-plate. Like reference characters indicate like partsthroughout the several views.

Referring to the drawings, the main body of an escutcheon-plateembodying my improvement is indicated by the reference-letter a, and itis so formed and proportioned that when applied to a door b in itsproper position in relation to its lock 0 a portion of it projectsbeyond the edge of the door in position to overlap the face-casing cl ofthe door-frame when the door is closed, as shown in Figs. 1 and 3. Theportion of the plate thus overlapping the casing may extend'the entirelength of the plate, as shown, or may be a projection from the main bodyof the plate, and is provided with a tooth or detent e, projecting fromits back surface for en gaging with the face-casing dby enteringa cavityf, formed therein for receiving'it when the door is closed.

the bolt more difficult.

The plate may be well secured to the door by escutcheon-pins extending.through the door and clenched; but 'a preferable way is to secure it inthe manner shown in the drawings by screws g, extending through the doorfrom the back side and threaded into bosses h, formed on the back sideof the plate for receiving them,

While the escutcheomplateshown is for a key-lock," it. is to beunderstood that my invention is not limited thereto, but maybe embodiedin the escutcheon or knob plates of permutation-locks as well.

Thisimprovedescutcheon-plate adds to the security of the lock with whichit isused by interlocking with the face-casing of the doorframe, thusmaking it much more difficult to pry the door and the door-jamb apartibymeans of a thin lever thrust into the clearance-space between them andwith springlocks by covering the joint between the door and .-theface-casing, thus makingaccess to What I claim as'myinvention, anddesire to secure by-Letters Patent, is

1. An 'escutcheon-plate formed and proportioned to project beyond theedge of a door when properly applied thereto; the part for. projectingbeyond the door formed to inter lock with the door-frame, substantiallyas set forth. 7 e

2. An iescutcheon-plate formed and proportioned to project beyond theedge of a door when properly applied thereto, and having bosses forreceiving retaining-screws; the part for projecting beyond the doorformed to interlock with the door-frame, substantially as shown anddescribed. I
